As to the modernity of ammunition, I have been using Federal 9BP in a variety of 9mm pistols for good many years. I do not recall having ever had a failure to feed, fire, or function. I know I can buy higher velocity and more expansion and sexy product labels, but it would be hard to regain that level of confidence in Something Else at any reasonable cost in time and money. I am reworking my .45 arsenal in search of something that will not kick me into a flinch in a Commander magazine full. It seems that just barely Major power factor is my personal maximum and I would not mind something along the lines of the gunzine article about .45 Lite. I have a handload that suits, but that brings up THAT debate.
